I-Iaving fully described my invention, what` I claim as new,and desire to secure by Letters Patent, is-

1. The combination in a carbureting apparatus, of a hydrocarbon-chamber, means .for passing air over the hydrocarbon-chamber' and means for regulating the extent of the hydrocarbon-chamber exposed to the air passing over it.

2. Acarbureting apparatus havingahydrocarbon-chamber and a chamber above and communicating therewith and an adjustable tube disposed in `said upper chamber and. adapted to communicate therewith and regu-l late the extent of the hydrocarbon-chamber` exposed to the air passing through said tube.

3. In a carbureting apparatus, the combi-` nation of a hydrocarbon-chamber andan air-4 chamber having an elongated openingconr. municating with the hydrocarbon-chamber, a longitudinally adjustable tube in the airchambeil and constituting a valve to close communication between the air and hydrocarbon chamber, and a check-valve control-` ling the outlet of air from said tube.

4t. In a carbureter, the combination with a tank or receptacle for hydrocarbon and a pipe or tube communicating with the `upper portion of said tank or receptacle at one end thereof, of an air-inlet tube in alinement `'with said first-mentioned tube or pipe, and means for adjusting said air-inlet tube longitudinally. v

5. In a carbureter, the combination with a` tank or receptacle for hydrocarbon and a `pipe or tube communicating with said tank or `receptacle at one end thereof, of an air-.inlet tube in said tank or receptacle in alinement with said rst-.mentioned tube or pipe, means for adjusting said air-.inlet tube longitudinally, a check-valve in said air-inlet tube and packing-rings between said air-inlet tube and the tank or receptacle.

6. In a carbureter, the combination with a tank or receptacle `adapted to contain hydrocarbon and a Wick filling or packing in said receptacle or tank, of a cover for said tank or receptacle, a cylindrical chamber on said cover communicating with the tank throughout the greater portion of its length, a pipe into which said chamber converges at one end, rin secured in said chamber and spaced `apart,au air-inlet tube disposed in said rings, packing-rings between said tube and cham-- ber at one end, a :rack `connected with said tube and apinion meshing with said rack and adapted to operate the same and the air-inlet tube `to .move the latter longitudinally in the cylindrical chamber.

7. In a carbureter, the combination with a tank or `receptacle adapted to contain hydrocarbon and a wick-filling, of a cover for saidtank or receptacle, parallel chambers on said cover communicating with said tank or receptacle, a pipe at one end of said receptacle into which both of said chambers converge, an airinlet tube in each chamber having one end projecting therefrom, a cross-head connecting the outer ends of said tubes, a rack connected to said cross-head and a pinion meshing with said rack and adapted to move the tubes longitudinally, substantially as and for the purpose set forth.

In testimony whereof I have signed this speciiication in the presence of two subscribing witnesses.

IVM. A. SCHMIDT.
